    Notes: This paper presents a model developed for the planning and control of a Ph.D. program in business administration at a major southeastern university. The technique employed was network simulation (GERT-type) which was selected for its capability to incorporate the stochastic nature of the system into the model. Included in the model are all the sequential steps of the Ph.D. program, such as course work, written preliminary exams, oral exams, dissertation and oral defense, as well as the various probabilistic outcomes and feedback loops of the process. The simulation output yields statistical estimates on program duration and probabilities of various outcomes. The model and simulation results can be used by both university administrators and Ph.D. candidates for planning purposes. The model is flexible in that it can be altered to reflect the unique features of Ph.D. programs of most schools.

    Notes: Most prior studies that examine in-process inventory requirements associated with a manufacturing facility employ an optimizing algorithm; this article proposes a heuristic procedure for determining such requirements. A procedure is given for determining “active” and “banked” work-in-process requirements. The two are combined to give total in-process requirements.A key factor presented in the paper is the relationship between in-process inventory requirements and the “balancing” of a production facility. Most prior researchers examine these problems independently. It will be shown that both problems can be resolved concurrently. The concepts are applicable to both an existing as well as a new manufacturing facility.

    Notes: Traditionally decision sciences has been plagued with the problem of implementation, i.e., transforming a sound theoretical technique into an operational system. Most researchers who study the problem concentrate on identifying factors which relate to implementation or on identifying the change process required to achieve implementation. In a recent study, Sorensen and Zand [24] demonstrate that the Lewin-Schein change theory explains the process necessary for achieving implementation.While the Lewin-Schein theory explains the required change process, the theory does not address the question of how one brings about change. The purpose of this article is to describe a “gaming” approach for accomplishing change. A case example is given to demonstrate the proposed implementation methodology.

    Notes: Research relating to sequencing rules in simple job shops has proliferated, but there has not been a corresponding proliferation of research evaluating similar sequencing rules in more complex assembly job shops. In a simple job shop, all operations are performed serially; but an assembly shop encompasses both serial and parallel operations. As a result of the increased complexity of assembly shops, the results associated with the performance of sequencing rules in simple job shops cannot be expected for an assembly shop. In this paper, 11 sequencing rules (some of which are common to simple job shops and some decigned specifically for assembly shops) are evaluated using a simulation analysis of a hypothetical assembly shop. The simulation results are analyzed using an ANOVA procedure that identifies significant differences in the results of several performance measures. Sensitivity analysis also is performed to determine the effect of job structure on the performance of the sequencing rules.

    Notes: The Japanese “just-in-time with kanban” technique reduces in-process inventory to absolute minimal levels, in concert with the Japanese belief that inventory is an unnecessary evil. Due to the success of Japanese firms that employ this type of system, American firms would like to import this technique and emulate Japanese successes. But this Japanese success may be attributable not only to the just-in-time with kanban technique but also to the production environment in which the technique is employed. This paper simulates the just-in-time with kanban technique for a multiline, multistage production system in order to determine its adaptability to an American production environment that might include such characteristics as variable processing times, variable master production scheduling, and imbalances between production stages. The results have practical implications for those firms considering adoption of the Japanese technique.

    Notes: In recent years the reported successes of Japanese production systems, particularly the just-in-time approach to inventory control, has caused managers to focus more of their attention on efficient decision-making procedures for determining production schedules that minimize inventory costs. One such potential area of attention is the economic lot-scheduling problem (ELSP), which occurs in a variety of manufacturing environments where machining operations are prevalent. The economic lot-scheduling problem addresses the determination of lot sizes for N products with constant demand (and cycled through one machine with a given production rate) to minimize setup and inventory costs. The most successful solution approaches to the ELSP have been based on the concept of a basic period that is of sufficient length for the production of all items, even though each item might not be produced during each repetition of the basic period. This paper proposes a heuristic approach to the solution of the ELSP (referred to as the method of prime subperiods), which is an extension of the basic period approaches. The procedure is described and demonstrated via an example and then tested using a set of six example problems previously employed in the literature related to the ELSP. The results indicate as good or superior performance by the proposed method of prime subperiods.

    Notes: This article reports the results of a survey of 101 UK company boards designed to obtain information on the extent of their strategic involvement, the style of strategy making, the planning process and the methods used to monitor and control the implementation of strategy. There is much prescriptive work on the need for boards to be involved in the strategy making process, but little empirical evidence has been gathered about current practices. This article makes a contribution to this debate. With Pettigrew (1993) we aim to avoid placing this research within any one research tradition, but attempt to provide descriptive results which increase our understanding of the board's role in strategy based on initial findings from an on-going study.
